Answer:
x = y = 60
Explanation:
You want the values of angles marked x° and y° in the given figure involving equilateral triangles and parallel lines.
Triangles
All of the triangles in the figure are congruent equilateral triangles. Each of their internal angle measures is 60°.
x° = y° = 60°

Additional comment
The (inside) base angles of the outside two triangles are alternate interior angles with respect to the top two angles of the center triangle. Hence they are congruent. The center triangle is marked as equilateral, so its angles are all 60°. That means all of the acute angles in the figure are 60°.
